TSOFF[6:0]:
These bits give a binary number to define the channel offset. The channel offset is between the framing pulse on the TSFS/MTSFS pin and the
start of the corresponding frame input on the TSD/MTSD pin. The signaling bits on the TSIG/MTSIG pin are always per-channel aligned with the data
on the TSD/MTSD pin.
In Non-multiplexed mode, the channel offset can be configured from 0 to 23 channels (0 & 23 are included). In Multiplexed mode, the channel off-
set can be configured from 0 to 127 channels (0 & 127 are included).

EDGE:
This bit is valid when the CMS bit (b2, T1/J1-042H) is ‘1’.
= 0: The first active edge of TSCK/MTSCK is selected to sample the data on the TSD/MTSD and TSIG/MTSIG pins.
= 1: The second active edge of TSCK/MTSCK is selected to sample the data on the TSD/MTSD and TSIG/MTSIG pins.
BOFF[2:0]:
These bits give a binary number to define the bit offset. The bit offset is between the framing pulse on the TSFS/MTSFS pin and the start of the
corresponding frame input on the TSD/MTSD pin. The signaling bits on the TSIG/MTSIG pin are always per-channel aligned with the data on the TSD/
MTSD pin.
